Abstract:
The Li and Ti doped NiO-base ceramic is prepared through a sol-gel process of preparing Li doped NiO precursor powder and subsequent mixing with TiO2 and sintering. The precursor powder prepared through sol-gel process has msll grain size and homogeneous chemical performance, and is easy to sintered and favorable to raising material performance. Regulating the doped Li and Ti amount can alter the dielectric performance of the ceramic material for different requirement. The ceramic has very high dielectric constant, greater than 10 to the power 4 at 1-10 MHz, and high temperature stability and may be used in thermoelectric electricity generation, thermoelectric refrigeration, producing high-density capacitor and other fields.
